A ro-langs (Tibetan: རོ་ལང) is a zombie-like creature from Tibetan folklore. Ro is the word for corpse and Langs is the perfect tense of "to rise up", so Ro-Langs literally means "a risen corpse". A ro-langs is usually created by a gdon spirit, or a sorcerer. A ro-langs cannot speak or bend over, it signals its victims by wagging its tongue back and forth. They can not bend any joints, which makes them walk with a stiff-armed lurch. In regions of Tibet there are low doorways to keep the ro-langs out.
